TOQALL WHOM 1T MAY OONCERN:

Be it known that I, JAMES A. SINCLAIR, oi'V Woods-field, in the countyof Monroe, and State of Ohio, have invented a new and improved FlourSitter; and I do hereby declare that the following is a, full, clear,and exact description thereof, which will enable those skilled in theart to make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which-- Figurel is avertical longitudinal section ot' my improved sitter, taken through theline x x, iig. 2.

Figure 2 is a vertical cross-section of thc same, taken through the liney y, tig. 1.

Similar' letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved machine forsifting tlour, meal, or screening grapes, cherries, berries, grain,seeds, dto.; and it consists in the combination of the two cylinders,having lines of brushes winding spira-lly about them in oppositedirections with the sliding drawer; in the combinationof a removablescreen or sieve with the sliding drawer; in making the sliding drawer intwo parts hinged to each other at their side edges; and in thecombination of the sliding drawer with the hopper and dischargingspouts; the whole being constructed and arranged as hereinafter morefully described.

A is the box or frame of the sitter, thc upper part of which is formedinto a hopper, B; the bottom or discharging orice of which is wholly orpartially closed by the slide C, which is operated by the rod D passingout through the end ofthe box A, as shown in iig. l, so that the flouror other substance being sifted or screened may be admitted to the sievewith any desired rapidity. E is a drawer which slides in and out throughan opening in the ond ot' the box A, and which is secured in place bythe button F pivoted to the said box. The box E is made in two parts, eland ce, as shown in figs. 1 and 2, which parts are hinged vto each otherat their rear side edges; andthe upper part or cover el has a hole outthrough it corresponding to the discharging orifice of the hopper B, Gis the sieve or screen, the ends of which arev securely attached to theend blocks gl and g2,

and which is removably secured in place by screws passing through thesides-of4 the drawer E and into the said end blocks gl and g2, so thatthe sieve may be readily changed Vfor a. iner or coarser one, as may bedesired. H and I are cylinders, the journals of which revolve inhearings in the ends of the drawer E, as shown in tig. l. J is a crankattached to the projecting end of the journal of one ofthe cylinders, asH, by which motion is communicated to said cylinder'. Motion iscommunicated from the cylinder H to the cylinder 'by gear-wheels, K, oneot which is shown in fig. 1,. attached to the end of each of saidcylinders, and the teeth of which mesh into each other.' L is apartition passing across the end of thevdrawer E, and which prevents theflour or other substance being sifted or screened from coming in contactwith the gear-wheels K. M are brushes arranged in spiral lines aroundthe cylinders H and I, which spirallincs wind lin a different directionin the one cylinder from what they do in the other, so that thctendency' of the said brushes may be to move the lumps and othersubstances that cannot pass through the sieve back to its rear end,where they escape through the spout N into a. receptacle prepared fortheir reception. Ois a wire o r rod passing longitudinally across themiddle part of the sieve G to support said middle part, and cause theparts of the sieve on each side of said rodrO to take 'a semicircularshape so as to more nearly conform to the form of the cylinders H and I.

I claim as new, and desire to secure by Letters Patent- 1. Thecombination ofthe two cylinders H and I, having lines of brushes Mwinding spirally around them in opposite directions with thesliding'drawerE, substantially as herein shown and described and for thepurpose set forth.

2. The drawer E, consisting of two hinged parts, el and e2, with openingon its upper side registering .with the discharge orifice of the hopper,and having at its bottom the semi-cylindrical sieve G swept by thespiral brushes M, and a passage at its rear opening-into spout N, andconstructed and operating substantially as described for the purposespecified. n

3. The combination of thc sliding drawer E with the box A, hopper B, andspout N, substantially as herein shown and described JAMES A. SINCLAIR.
